ADJUSTABLE BANDING-BOARD.

Specification of Letters Patent.

Patented Nov. 22,1921.

To all'wlzom it may concern:

Be it known that I, J OHN F. KENNEDY, a citizen of the United States, residing at Baltimore, in the State of Maryland, have invented certain new and useful Improvements in Adjustable Banding-Boards, of which the following is a specification;

This invention relates to certain new and useful improvements in what are known as banding boards upon which rubber strips are manufactured into bands, and it more especially relates to a board of the character indicated, mounted so as to be capable of rotatable movement and thus facilitate the making of the comparatively thin, wide rubber bands necessary to form the plies to be used in that part of pneumatic tires immediately adjacent the outer layer of canvas or other foundation fabric forming the casing. i j

As heretofore constructed it has been necessary in the manufacture of such bands either to have a number of machines each for a different size band, or one machine with a number of band boards of different lengths which were capable of being detachably mounted upon or demountedfrom a single machine.

One of the objects I have in view is to overcome the present disadvantages and loss of time necessary to mount or demount the band board from theframe upon which it is located whenever a change in size is necessary. This I do by providing a board adapted to] be readily adjusted or extended to different lengths so that but one board will be necessary for the manufacturecf different sized bands.

binations tobe hereinafter, set forth and claimed, with' the understanding that the several necessary elements comprising my ,invention, may be varied in construction,

proportions and arrangement, WitbQutoil the same. hub of a wheel 9 which is mounted upon the shaft 6. This wheel has spokes ll connecting the hub with the rim 12, the periphery parting from the spirit and scope of the appended claims. r

In order :to make my invention more clearly understood, I have shown in the accompanying drawings means for carrying the same into practical eifect, without limiting the improvements in their useful applications to the particular constructions, which for the purpose of explanation, have been.

madethe subject of illustration.

In the accompanying drawings:

Figure 1 is a side view of my improved device.

Fig. 2 is a plan view thereof.

Fig. 3 is a view showing the constructio in detail of the wheel for rotating the band board and the means for locking the said board in rotative position.

Fig. 4 is an enlarged perspective View of the extension or insert block.

Thenumeral 1 refers to the bottom or bed plate of a metallic framefrom whichextend upwardly at each end side pieces 2, which are connected together by a metallic top plate l, the side andtopplates preferably being cast integral withthe bottom plate and the latter being provided with several apertures through which bolts extend to secure it to the floor or bed block.

Secured uponthe top plate 4 by bolts l 6 may be readily turned thereby, should it become hard to turn through neglect to The numeral 9 refersto the of which. is provided with teeth 13. The object of the shaft 6 is to support the sleeve board 14 and said shaft extends transversely through the board and extending parallel therewith are supplemental supporting rods 15 one end of each of which is screwed into one of the spokes l1 andthe other end of which extends through a hole in the sleeve board. r i

In order to insure that the supporting shaft and the supporting rod shall fit tightly within, the sleeve board and not slip when the board is turned, they are made square in re -s c n ar lik w he holes through which they pass, the outer ends of each of the rods being provided with a winged nut or thumb screw 16 whereby the board may be drawn up tightly agiainst the wheel 9 located on the opposite S1 6.

Mounted upon thetop plate d adjacent the journal box 5 and forming an integral extension thereof is a hollow block 20 and within the block and surrounding a rod 21' extending therethrough is a spiral spring I r 22 one end of which is attached to the rod 21 and normally presses said rod in the direca tion of the arrowf'This rod21 is provided with a knob 22 at one end, by means of which it may be pulled the opposite direction.

"The other end or the rod '21 isenla'rged as even when the edges of the plunger lies be tween the teeth but loeks it against reverse movement. By turningthe plunger, how ever; so that its diagonal edge will be oppositely disposed-tothat shown, the wheel is locked from turning in the opposite direction l The numeral ldorefers to the sleeve board which is of rectangular configuratio n in cross section; one end is squared oii as at 31 and the other end isrounded off as at 82 The interior of the sleeve'board is hollowed out as indicated in the dotted lines 33 (see Fig. 2), and adapted to fit therein'and to slide in and out,j is an extensible and adjustable board 34; It will be observed, however, that the extensible member 34: is considerably smaller thanthejboard within which it fits being approximately of the size of the hollowed out portion of thelatter. r

The outerend of theeXtensible member. is"

provided with an end board 35. This board on its inner face 36 is of the same superficial area in cross section asl'the banding hoard proper and its outer face is of rounded contour to correspond with the other end 32 of the sleeve board. Attached to one side of this end board 35 is a metallic adjusting strip wise. The strip is provided for the greater portion of its length with a slot 38 so as to permit such slotted end to readily slide over a stationarily mounted worm'shaft 39 1 1 Upon the shaft i'sa worm wheel'aiO adapted totrav'el upon the worm shaft 379 and adaptprojecting from the side of the sleeve board.

ed to push the metallic strip" 37 'tightly' aga nst the sleeve board and hold'it at' any point whlch may be selected for adj ustin'e'nn and wheel.

The" reference numeral 4-1 indicates an insert block to be used in connection with the banding board. It is of the same shape and size in cross section and is interiorly reamed out'as seen in Figfll, so as to enable it to slide over the extensible member 34. i l

' It is proposed to have a number of interchangeable insertbloclis, each of a diiierent length," through any one of which the ente'nsiblemember is adapted to he slipped until the insert block is in contact with the end bOZl-ICl35, when the extensible memb r's pushed in the opening in the sleeve'board.

One face or the block then contacts with the sleeve board and the other face with the firmly down against the insert block and the adjusting wheel brought tightly against the .metallic strip 37 "'soas"tohold firmly and the sleeve board and the several units to be used therewith,

can be readily moved in one direction by the workman simply pushing against it while engaged in his work. move the board in the opposite direction, the 7 spring operated 'p'lunger' between the teeth 27 Inustfeithe'r' be withdrawn or reversed in position. The bands in" the making extend Should he desireto nd board' The end board is then pushed around" one end oi? the sleeve board to the other and back again and the workman turns the board as'the work progresses; and when he desires to makebands which are longer or shorter than those he is working on, the
